It was surprising to me that this thread didn't already exist, so I checked back through over a month of posts, and still didn't see it. My apologies if there's an even older thread that I didn't see, but if that's the case, surely new posters (like myself) have arrived since then and would also like to contribute!
What are your hopes for the races in FFXIV? What race do you want to play as?
Personally, though it can be limiting, I liked the way that each race had their own strengths and weaknesses. It just makes sense that a Galka/Roegadyn would make a better tank than a tiny Taru/Lalafell.
I'll probably be playing a Lalafell in FFXIV, because I like dealing damage more than taking it- though I'm considering Miqo'te to give myself more options.
